signor to Trussell Manufacturing Company, Poughkeepsie, N. Y., a corporation of New York 5 5 Application September 4, 1936, Serial No. 99,353

3 Claims.

This invention relates to binders and is a partial continuation of the Clarence 'D. Trussell patent application entitled Sectional binder, Serial No. 77,337, filed May 1, 1936.

Particular objects of the present invention are to provide improved means for securing wirebound refills within a cover or other form of mounting or support. Such improvements relate mainly to facilitating the insertion and locking or securing of the refillwithin the cover structure.

Other and relatedobjects are to provide a simple and inexpensive structure for the purpose,

which can be readily manufactured and assembled, be easy to operate, and which will be entirely practical and effective.

The foregoing and other desirable objects are attained in this invention by the novel features of construction, combinations and relations of parts hereinafter described and claimed.

The drawing accompanying and forming part of the following specification illustrates one of the present preferred commercial forms of the invention, it being understood that the structure may be modified and changed as regards such particular illustration, all within the true intent and scope of the claims;

Fig. 1 is a broken end view of one of the binders.

Figure 2 is a broken cross sectional view of the same.

Figure 3 is a broken face View showing the binder in opened relation.

Figure 4 is a broken longitudinalsectional view, substantially on the center line of the binder, such as line 44 of Figure 3 but illustrating the operation of inserting or removing the refill.

Figure 5 is a similar fragmentary View showing the slide element shifted to secure the refill in position.

In the form of the invention shown, the pages, leaves or sheets H) are held together by rings connected as portions of a continuous length of spring wire and made up of spaced substantially parallel strands I6 connected by rounded loops ll, Figures 3 and 9, with individual strands of the adjoining ring elements joined by intervening connecting loops I8. This parallel strand construction gives the rings an inherent spring quality advantageous to the purposes of the present invention.

The holder or support for the bound leaves is shown as a book back I9 having front and back covers 20, 2|, and the connection with this supporting member is efiected by engaging the binder rings with certain hook elements on the back.

The binder rings are entered in the notches 22 in the arched portions and substantially parallel sides-of an inverted U-shaped housing 23, having outwardly projecting flanges 24 at the open side of the same, secured flatagainst the back as by'rivets or other suitable fastenings 25. Operating in this housing there is shown a slide 26 of similar U-shaped form having notches 21 in the arched and side wall portions of the same, to register, in one position of the silde, with the notches 22 in the housing, as-in Figure 4 and, in another position of the slide, Figure 5, to be enclosed within intervening solid portions 28 of the housing. At one side of the notches in the slide, hook elements 29 are provided which in the first position of the slide, Figure 4, are housed and concealed within the solid portions 28 of the housing and, in the second position of the slide, Figure 5, project across from one solid portion 28 to the next so as to bridge and close the housing slots 22.

Thus, it will be seen that with the hooks retracted as in Figure 4, the rings of the refill l5 may be readily slipped into the housing notches 22 without being impeded or obstructed in any way and that after being'so engaged in the notches the slide may be shifted upwardly from the position indicated in Figure 4 to that shown in Figure 5, to close the notches by the hook portions 29 of the slide, which then extend through and secure the rings to the back. The double spring strands I6 of the rings may yield toward each other, if

necessary, to fit closely within the receiving notches 22 and the U-shaped housing and slide may be folded to such shape of more or less resilient sheet material, and thus have a yielding spring fit one within the other, accommodating for variations in manufacture and causing the slide to operate smoothly and yieldingly hold its different positions in the housing. The double thickness of the slide also gives it desired strength and stability and reinforces the housing so that both these parts may be made of relatively light inexpensive folded sheet material. 7

To further guide the slide and to stiffen and reinforce both this and the enclosing housing, said slide may be constructed with outstanding flanges 3|] at the open side of the same, and the sion of these lugs in this Way also stiffens and reinforces the ends of the slide.

The arched construction of the two members, that is, the housing and the slide, provides a relatively narrow and strong form of anchorage adapted for small as well as large books. in which the binder rings may be quickly and easily entered, and forms a construction which can be readily manufactured and assembled at low cost.

I claim:

1. A binder of the character disclosed comprising in combination, spaced binder rings, a housing of sheet material folded longitudinally and having notches in the folded edge of the same spaced to receive said binder rings and a longitudinally folded slide operating in said housing having notches corresponding to said notches in the housing and hook elements at one side of said slide notches to close the notches in the housing and an angularly turned handle integrally con- 1 nected' with the longitudinally folded sides of said slide, the material of said angularly turned handle extending from the opposite folded sides of said slide and bent backward therefrom beyond the arch of said folded slide to reinforce and brace said sides in their folded relation and to project beyond the arch of vthe slide. 1

2. A holder for a refill of the character disclosed comprising a longitudinally folded housing of sheet material having attaching flanges at the open side of the same and notches in the folded edge portion of the same, a correspondingly folded slide operating in said housing having notches to register with the housing notches and hooks at one side of said slide notches to extend across the housing notches, said slide having angularly bent flanges at the open side of the same and. said housing having shouldered seats in the flangesof the same for slidingly receiving said slide flanges.

3. A binder comprising spaced binder rings, said rings consisting each of spring strands connected in spaced substantial parallel relation, a

longitudinally folded housing of sheet material having notches in the arched portion of the same spaced in accordance with the spacing of said binder rings and of a Width each to receive the two spaced strands of one binder ring, a correspondingly folded slide of sheet material in frictional sliding engagement in said housing and notched in the arched portion of the same to register with said housing notches and with projecting portions at one side of said slide notches to each extend through a pair of the ring strands in one of the'housing notches, said spring strands of the rings being spaced sufiiciently to yieldingly and frictionally engage the opposite sides of the notches in which they are entered, and means for shifting said slide in the housing to extend said projections through the pairs of ring strands or to retract said projections and leave said pairs of ring strands frictionally held only in the notches by their spring tension;
